I've owned lots of Linn stuff.
Not sure how efficient your speakers are, but the linn will be quite a step down in power from the multi5. I think the Linn pre-amp section would be better than the NAD, so you are trading up in pre amps and down in power amps.
Linn wire only works in an all Linn system (amp and speakers) and bi-wiring usually adds nothing so that is kind of a wash.
The Oppo will be better for blueray than the Sony, but inferior to the Linn classik for CD playback.
So I'm not sure you are gaining much in the end with these changes. It will just be different.
Sounds like you are just making changes to make changes.
